I have a standard analog POTS service attached to a TDM401 card. My zapata.conf for this line has: ; PSTN connected here ;immediate=no ;busydetect=yes ;busycount=8 ;musiconhold=default mailbox=100 mwimonitor=fsk mwilevel=512 mwimonitornotify=/usr/local/sbin/zapnotify.sh faxdetect=incoming signalling=fxs_ks context=incoming callwaiting=yes callwaitingcallerid=yes channel => 4 When I'm on the phone and another call comes in, I hear the callwaiting tone. However, Asterisk doesn't appear to give me any CallerID information for the other call. Is there some way I can gain access to the CallerID info on the other call? I assume there is some extensions.conf magic required? An old CallerID box can do this, so I would expect Asterisk to be able to do this too. Any advice appreciated. Best, Jim
